PRIORITY

This application claims the benefit of a provisional application U.S. Ser. No. 60/772,288 filed in then names of Eugene and Michelle Nasuti on Feb. 10, 2006.

FIELD OF THE INVENTION

This invention generally relates to utility trays for lifts and more particularly, to scissors lifts.

BACKGROUND OF THE INVENTION

Scissors lifts are generally known in the art and used in a variety of construction related trades. Reference is made, e.g., to U.S. Pat. Nos. 3,983,960 (Scissors Lift), 6,257,372 (Scissor Lift and Method for Using the Same), 5,722,513 (Scissor Lift), 4,113,065 (Scissors Lift), 4,175,644 (Scissors Lift), 5,490,754 (Hydraulic Upper Deck for a Trailer), 6,651,775 (Low Level Scaffold with Ballscrew Drive), 4,930,598 (Scissors Lift Apparatus), 6,761,248 (Adjustable height platform suitable for installation on a vehicle), 4,558,648 (Energy recycling scissors lift), 4,899,987 (Vehicle scissors lift), 5,394,959 (Scissor lift apparatus for work platforms and the like), 4,491,449 (Load raising vehicle and method), 3,785,462 (Scissor Lift and Drive Mechanism therefore), 6,425,459 (Aerial work platform apparatus with anti-tipping supplement), 6,050,365 (Scissors-type work platform lift machine with electromechanical based lift actuation arrangement), 5,695,173 (Scissors lift platform with electronic control), 5,145,029 (Self-storing maintenance stand for a scissors lift aerial work platform), 6,044,927 (Work platform lift machine with scissor lift mechanism employing telescopable electro-mechanical based lift actuation arrangement), 4,867,277 (Portable lifting device and cart), 4,114,854 (Scissors lift work platform) and 3,831,713 (Platforms System for Servicing Aircraft Landing Gear). The disclosure of each of these patents is incorporated by reference into this specification.

These and similar apparatus are also commonly known as snorkel lifts, knuckle lifts, man lifts, scaffolds, aerial work platforms, low-level scaffolds, platform lift machines, hydraulic decks, mobile work platforms, adjustable height work platforms and other names and nicknames known to those of ordinary skill in the art. These devices are commonly used by tradesman such as masons, carpenters, painters, carpet layers, roofers, electricians, plumbers, HVAC technicians, utility workers, and the like. These devices are also commonly used in the storage and transport of materials in commercial and industrial settings.

Generally, scissors lifts comprise a working platform, e.g. a deck, surrounded at its periphery by vertical and horizontal members, e.g. guard rails or safety railings that operate as a safety feature to enclose workers and protect against falls from the elevated surface of the deck. While presumably adequate for their intended purpose, they have drawbacks in their limited functionality. It is frequently necessary for workers in the scissors lifts to access tools and small parts to complete their work, e.g., wire cutters, hammers, pipe wrenches, screwdrivers, screws, bolts, tape, clamps, nails, drills and the like. In some applications, workers also require access to materials such as wire, pipe, lumber, roofing tiles, conduit and the like.

The work platform, or deck, has limited storage space due to its compact size. As a result, workers often repeatedly enter and exit (dismount and re-mount) the deck to access these small tools and other items, creating additional safety concerns with unnecessary movement about the elevated work surface. This frequent activity also creates wear and tear upon the scissors lift as well as inefficient and costly labor delays in completing assigned work tasks. Additionally, using the deck for transport and storage of tools and materials can create a safety hazard and an obstruction to the worker.

While the practical utility of utility trays is generally known, none of the existing devices may be suitably adapted to the unique configuration of the scissors lift. Reference is made to U.S. Pat. Nos. 4,489,837 (Mechanic's creeper support and utility tray), 4,515,242 (moveable hand railing and tray for ladders), 4,874,147 (tray and tool holder adaptable to stepladders), 5,312,002 (utility tray), 6,237,799 (utility tray), 5,836,557 (detachable utility tray for step ladder), 6,098,748 (adjustable height tool bin system), 5,915,646 (cart for carrying spools of wire and utility trays), 5,967,259 (utility tray for stepladders), and 6,902,034 (apparatus with utility tray mounted to scaffold). The disclosure of each of these patents is incorporated by reference into this specification.

Rigidly attached utility trays would not take into account various angles of position of scissors lift members or would not always be in the optimum orientation for maintaining tools and supplies for ease of use.

Existing moveable mounts for utility trays do not adequately protect against rotational movement, e.g. swaying, during the taxiing of the scissors lift, and the emptying of the contents of the utility tray.

There is needed a device or system that can obviate or mitigate the aforementioned safety concerns while simultaneously enhancing the convenience and efficiency of the deck workspace for the tradesman working in a scissors lift.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

In accordance with this invention, there is provided an anti-sway stabilizer accessory support means and a utility tray assembly 100 which may be readily attached to a scissors lift 150 to provide convenient storage of frequently used items by a worker. FIG. 1 is a perspective view of the utility tray assembly 100 comprising a tray mount 102 and a utility tray 104 as it is mounted for use upon the scissors lift 150. The utility tray 104 is adjustably mounted to the tray mount 102. The tray mount 102 in turn is adjustably mounted to the scissors lift 150.

Referring to FIG. 1, the scissors lift 150 includes a horizontal deck 106 (working platform) partially enclosed by an upwardly depending safety support frame 108. Said safety support frame 108 includes a plurality of vertical members 110 and one or more horizontal members 112. The horizontal members 112 are connected between at least two of the vertical members 110. Said safety support frame 108 further includes a means of ingress and egress 114 to the horizontal deck 106.

As used in this specification, vertical members 110 shall mean a structural or supporting member that vertically extends from horizontal deck 106 or platform of scissors lift 150 or comparable apparatus, and shall include posts, rods, guardrails, safety railings, stanchions, beams and the like.

As used in this specification, one or more horizontal members, such as horizontal member 112, 112A, shall mean a structural or supporting member that extends between any two vertical members of horizontal deck 106 or platform of scissors lift 150 or comparable apparatus, and shall include posts, rods, guardrails, stanchions, safety railings, beams and the like.

Oftentimes, workers utilize a portion of the horizontal deck 106 as an impromptu staging area. As used in this specification, staging area shall mean any portion of a deck or platform, or attachment thereto, that is used to temporarily collect and organize, marshal or stage construction-related tools and materials. As will be apparent, the use of any portion of the deck for storage creates an obstruction and safety hazard for employees while working at fairly substantial heights.

Referring again to FIG. 1, the tray mount 102 is adjustably mounted to the horizontal member 112 of the scissors lift 150 and engages the utility tray 104. In one embodiment, utility tray 104 may be outwardly depending and the support tray base is positioned perpendicular to the tray mount 102 as shown in FIGS. 2 and 3.

In an alternate embodiment, utility tray 104 may be downwardly depending and the support tray base is positioned parallel to the tray mount as shown in FIGS. 1, 4, 5, 6, 7 and 8.

In accordance with another embodiment of the invention, the utility tray 104, 104A may be positioned on the interior or exterior (protruding inwardly toward the horizontal deck 106 or protruding outwardly therefrom) from the safety support frame 108.

FIG. 2 is a perspective view of another embodiment of a utility tray assembly 200 mounted for use upon the scissors lift 150. The tray mount 102 is identical to that depicted in FIG. 1 but the utility tray 104A differs in its shape. In the embodiment depicted in FIG. 2, the utility tray 104A is outwardly protruding and mounted such that the plane of support tray base 202 is perpendicular to the tray mount 102. In an embodiment of the present invention, the plane of support tray base 202 is inclined at an angle to the tray mount 102.

Tray Mount 102

FIG. 3 is a perspective view of one embodiment of the utility tray assembly 200 depicted in FIG. 2. In an embodiment as depicted in FIGS. 1, 2 and 3, the tray mount 102 includes two anti-sway stabilizers (904 of FIG. 9A), however, it is to be understood that some embodiments of the present invention include only one anti-sway stabilizer (not shown) and yet other embodiments (not shown) include 3 or more anti-sway stabilizers. For simplicity in discussion, the features of one anti-sway stabilizer 904 will be described in detail, but it is to be understood that such description applies to a plurality of anti-sway stabilizers comprising the tray mount 102.

As depicted in FIGS. 1, 2 and 3, while in use, the tray mount 102 is moveably mounted over (e.g. straddling) at least one horizontal member 112 of safety support frame 108. In some preferred embodiments (e.g. depicted in FIGS. 3 and 9A), the tray mount 102 is disposed over at least one horizontal member 112, 112A of the safety support frame 108.

FIG. 9A depicts a side view of a tray mount along 1-1 of FIG. 8. FIG. 9B depicts a side view of an alternative embodiment of a tray mount along 1-1 of FIG. 8. FIG. 9C depicts one embodiment and way to attach tray mount to a utility tray as a magnified view of BB of FIG. 7. FIG. 9D depicts an alternative embodiment and way to attach a tray mount to a utility tray as a magnified view of BB of FIG. 7. FIGS. 9E, 9F, 9G and 9H depict a magnified view of portion AA from FIG. 3 with alternate configurations of receptacle apertures.

Referring to FIG. 9A, the tray mount 102 essentially comprises an anti-sway stabilizer 904 and accessory support (not visible from this view but see 902 in FIG. 9E) for a utility tray 104, 104A integrally formed together. The anti-sway stabilizer 904 functions as a guiding means to restrict the rotational motion of the utility tray assembly 100, that is, to restrict a circular path about the horizontal member 112. In one embodiment, the range of rotation is limited to from about 1 to about 30 degrees about the horizontal member 112.

The accessory support comprises a plurality of receptacle apertures 902 integrally formed into the structure of anti-sway stabilizer 904 (reference is made to AA of FIG. 3) functioning to receive a fastener 603 from mount receiver 916. (Reference is made to FIGS. 9E-9H and the accompanying disclosure.)

Referring again to FIG. 9A, utility mount 102 includes a suspending member 504, a first stabilizer member 506, a second stabilizer member 508, an inverted U-shaped cavity 908, a plurality of receptacle apertures (not visible from this view but see FIGS. 9E-9H), an engagement surface 910, a first contact surface 912, and a second contact surface 914.

Referring again to FIG. 9A, first stabilizer member 506 and second stabilizer member 508 function to manage deflection and hold the utility tray assembly 100 in a substantially fixed position about horizontal members 112, 112A. First stabilizer member 506 and second stabilizer member 508 function to inhibit or arrest rotational movement and prevent the scissors lift utility tray assembly 100 from swinging and releasing the contents of the utility tray 104A. The contents of the utility tray 104A may include one or more tools such as wire cutters, hammers, pipe wrenches, screwdrivers, screws, bolts, tape, clamps, nails, drills, aerosol cans, and the like.

Referring again to FIG. 9A and the embodiment depicted, in straddling the horizontal member 112, first stabilizer member 506 communicates with said horizontal member 112 at first contact point 914 and engagement surface 910. Referring again to FIG. 9A and the embodiment depicted, in straddling the horizontal member 112A, second stabilizer member 508 communicates with said horizontal member 112A at second contact point 912. Inverted U-shaped cavity 908 surrounds the horizontal members 112, 112A.

In other embodiments with a more precise fit, additional surfaces may contact horizontal members 112, 112A.

Referring again to FIG. 9A, when in use, the weight of utility tray 104A acts to cause first contact point at 914, engagement surface 910 and second contact point at 912, thereby preventing rotational motion about horizontal member 112.

In another embodiment depicted in FIG. 9B, inverted U-shaped cavity 908 surrounds horizontal member 112 but not horizontal member 112A. In such embodiment, first stabilizer member 506 has a length 928 less than the length (see 926 of FIG. 9A) of second stabilizer member 508. In such embodiment, first stabilizer member 506 of length 928 is sufficient to provide second contact point at 914 and adequately prevent the disengagement of engagement surface 910 from horizontal member 112. By way of example, but not limitation, length of the first stabilizer member 506 ranges from about 3 to about 8 inches.

The embodiment as depicted in FIG. 9B is most suitable for applications where the scissors lift is relatively stationary or there is nominal taxiing along flat surfaces. Since the embodiment in FIG. 9A incorporates first stabilizer member 506 surrounding horizontal member 112A, it would be more advantageous in applications where there is frequent taxiing or movement across uneven (bumpy) surfaces.

FIG. 9C depicts tray mount 102 and how it is fastened to utility tray base 502. In one embodiment, receptacle aperture 902 comprises a cylindrical channel having internal threads mating with the threads of a screw 603. The cylindrical channel creates a frictional engagement for the screw 603. In such embodiment, counterpart mount receiver 916 similarly comprises a cylindrical channel, however, optionally and preferably without threads. To mount the utility tray 104 to the tray mount 102, the mount receiver 916 of utility tray base 502 is aligned with aperture 902 such that screw 603 may be axially inserted through the mount receiver 916 and then threaded through receptacle aperture 902 to create a frictional engagement of the screw 603, thus adjustably securing the utility tray base 502 to the utility mount 102.

FIG. 9D depicts an alternate embodiment of aperture 902 of tray mount 102 and how it is fastened to utility tray base 502. In this embodiment, receptacle aperture 902 includes a first segment 920 and a second segment 954. First segment 920 includes a cylindrical channel that engages the screw 603. Second segment 954 includes a recess of sufficient volume to permit a bolt 956 to be countersunk below the surface as it frictionally engages the screw 603 and secures it about the receptacle aperture 902. In such embodiment, counterpart mount receiver 916 similarly includes a cylindrical channel that engages the screw 603. To mount the utility tray 104 to the tray mount 102, a mount receiver 916 of utility tray base 502 is aligned with receptacle aperture 902 such that the screw 603 may be axially inserted through mount receiver 916. The screw 603 is then inserted through receptacle aperture 902, and a bolt 956 is screwed on its end. The bolt 956 creates a frictional engagement of the screw 603, thus adjustably securing the utility tray base 502 to the tray mount 102. In another embodiment (not depicted), the mount receiver 916 and receptacle aperture 902 channels may contain internally threads mating with the threading of the screw 603.

The tray mount 102 is desirably formed of a metal, metal alloy, a plastic, rubber, synthetic rubber, rubber-like material, a polymer, or a composite material. It is preferred, but not required, that the material comprise any combination of wear-resistant, weather-resistant, anti-corrosive and water-repellant properties. By way of example, but not limitation, said tray mount 102 may be formed of a moldable high strength, impact resistant plastic material such as glass filled nylon or synthetic rubber. By way of another example, but not limitation, said tray mount 102 may be formed of aluminum or treated aluminum.

In one embodiment, the tray mount 102 is integrally formed as a unitary structure via a single molding process. In another embodiment, the utility tray mount 102 comprises two or more sections cooperatively assembled to the desired configuration. These sections may be, but it is not required that they be, permanently adhered to one another by means known to one skilled in the art.

In one embodiment, utility tray mount 102 comprises three sections, suspending member 504, a first stabilizer member 506, a second stabilizer member 508, each section 504, 506, 508 comprising squared light gauge steel of from about 1/16 to one inch, preferably about ½ inch squared light gauge steel, welded at the joints. First stabilizer member 506 joins suspending member 504. Suspending member 504 joins first stabilizer member 506 and second stabilizer member 508 and is disposed therebetween.

Referring again to FIG. 9A, it is preferred that the width of the opening 922 of inverted U-shaped cavity 908 be a distance sufficient to permit the utility mount 102 to straddle a horizontal member 112, preferably of from about 1 to about 3 inches.

Referring again to FIG. 9A, in yet another embodiment, these 3 sections 504, 506, 508 may be removably and adjustably joined together by means known to one skilled in the art. For example, a screw mechanism may be used to adjustably move first stabilizer member 506 and second stabilizer member 508 with respect to suspending member 504 to obtain the tray mount 102 with an opening of the desired width 922 to securely fasten the utility tray assembly 100, 200 to scissors lift 150. In embodiments where the first stabilizer member 506 is adjustable, the width of the opening 922 will correspond to the adjustable width of the tray mount 102. Other adjustable mechanisms known in the art may be suitably adapted to this application.

Referring again to FIG. 9A, in one embodiment, suspending member 504 comprises a length 924 of from about one to about 10 inches, preferably three inches, and thus, first stabilizer member 506 and second stabilizer member 508 are disposed a distance 922 of from about one to about 10 inches, preferably about 2.5 inches, apart (thus width 922 would be about 2.5 inches).

Referring again to FIG. 9A first stabilizer member 506 and second stabilizer member 508 have a length 926 of from about 12 to about 48 inches, preferably 24 inches, and are disposed substantially parallel to one another.

In one embodiment (not depicted), a non-skid surface is integrated into or affixed to the area about engagement surface 910, first contact surface 912, and/or second contact surface 914. Said non-skid surface may comprise rubber material, groves, serrations, ridges, spikes, bumps, depressions, fabric or the like. One may use any suitable surface or material that creates friction and assists in preventing the utility mount 102 from moving while in use.

Referring again to FIG. 9A and the embodiment depicted, the junctions of suspending member 504 with first stabilizer member 506 and second stabilizer member 508 are angular with substantially a perpendicular angle being formed. In another embodiment (not shown), the junctions of suspending member 504 with first stabilizer member 506 and second stabilizer member 508 are curved, forming a radius of from about one inch to about five inches, preferably a radius of from about one inch to about two inches.

In a preferred embodiment, a plurality of receptacle apertures 902 are disposed along first stabilizer member 506 and second stabilizer member 508 to facilitate the securing of the utility tray 104/104A to the tray mount 102. As will be apparent, the plurality of receptacle apertures 902 may be disposed about the stabilizer members 506, 508 in a variety of ways to accomplish their intended function. In some embodiments, a plurality of receptacle apertures 902 are only disposed along first stabilizer member 506 or a portion thereof. In yet another embodiment, a plurality of receptacle apertures 902 are only disposed along second stabilizer member 508 or a portion thereof.

Referring to FIGS. 3 and 9E, a section AA of FIG. 3 is depicted in magnified view in FIG. 9E. As depicted in FIG. 9E, a plurality of receptacle apertures 902 are longitudinally aligned, axially spaced along the stabilizer members 506, 508 such that the centerpoint 930 of each said receptacle aperture 902 is vertically aligned with the centerpoint 930 of the adjacent aperture and equidistantly spaced from first side 992 and second side 994. In one embodiment, the centerpoint 930 of one receptacle aperture 902 is spaced at a distance of from about one-half inch to about 6 inches from the adjacent receptacle aperture 902.

In one embodiment, at least one receptacle aperture 902 is located such that the centerpoint 930 thereof is disposed such that it facilitates a flush alignment of the top of the utility tray 104A and the top of suspending member 504 as depicted in FIGS. 3 and 9A. By way of example, in an embodiment with a utility tray 104A with a depth of 1.5 inches, at least one receptacle aperture 902 should be disposed at a point of no more than one and one-quarter inches from the first end 931 of second stabilizer member 508.

Other arrangements of receptacle apertures 902 are depicted in FIGS. 9F, 9G and 9H. As depicted in FIG. 9F, the centerpoint of aperture 960 and the centerpoint of aperture 962 are horizontally aligned with one another and equidistantly spaced from first side 992, second side 994 and one another 960, 962. Similarly, the centerpoint of aperture 964 and the centerpoint of aperture 966 are horizontally aligned with one another and equidistantly spaced from first side 992, second side 994 and one another 964, 966. The distance 996 between sides 992 and 994 is from about one inch to about twelve inches, preferably from about 1.5 inches to about 4 inches. These pairs (960 and 962 being a first pair and 964 and 966 being a second pair) are longitudinally aligned, axially spaced along the stabilizer members 506, 508. In one embodiment, these pairs (960 and 962 being a first pair and 964 and 966 being a second pair) are disposed at a distance of from about two to about twelve inches.

As depicted in FIG. 9G, the centerpoint of aperture 968 and the centerpoint of aperture 970 are vertically aligned with one another and equidistantly spaced from first side 992, second side 994. The centerpoint of aperture 968 and the centerpoint of aperture 970 are disposed at a distance of from about one-half to about two inches. Similarly, the centerpoint of aperture 972 and the centerpoint of aperture 974 are disposed at a distance of from about one-half to about two inches. These pairs (the centerpoints of apertures 968 and 970 being a first pair and the centerpoints of apertures 972 and 974 being a second pair) are longitudinally aligned, axially spaced along the stabilizer members 506, 508. In one embodiment, these pairs (the centerpoints of apertures 968 and 970 being a first pair and the centerpoints of apertures 972 and 974 being a second pair) are disposed at a distance of from about two to about twelve inches.

As depicted in FIG. 9H, the centerpoints of apertures 976, 980, 984 and 988 are vertically aligned. Similarly, the centerpoints of apertures 978, 982, 986 and 990 are vertically aligned. The centerpoint of aperture 976 and the centerpoint of aperture 980 are disposed at a distance of from about one-half to about two inches. Similarly, the centerpoint of aperture 978 and the centerpoint of aperture 982 are disposed at a distance of from about one-half to about two inches. Similarly, the centerpoint of aperture 984 and the centerpoint of aperture 988 are disposed at a distance of from about one-half to about two inches. Similarly, the centerpoint of aperture 986 and the centerpoint of aperture 990 are disposed at a distance of from about one-half to about two inches.

Referring again to FIG. 9H, the centerpoint of aperture 976 and the centerpoint of aperture 978 are horizontally aligned with one another and equidistantly spaced from first side 992, second side 994 and one another 976, 978. Similarly, the centerpoint of aperture 980 and the centerpoint of aperture 982 are horizontally aligned with one another and equidistantly spaced from first side 992, second side 994 and one another 980, 982. Similarly, the centerpoint of aperture 984 and the centerpoint of aperture 986 are horizontally aligned with one another and equidistantly spaced from first side 992, second side 994 and one another 984, 986. Similarly, the centerpoint of aperture 988 and the centerpoint of aperture 990 are horizontally aligned with one another and equidistantly spaced from first side 992, second side 994 and one another 988, 990.

The centerpoints of apertures 976, 978, 980 and 982 form a quadruplet of apertures. Similarly, the centerpoints of apertures 984, 986, 988 and 990 form a quadruplet of apertures. These quadruplets are longitudinally aligned, axially spaced along the stabilizer members 506, 508.
